Abstract: <P>PROBLEM TO BE SOLVED: To provide an apparatus for reducing harmonic distortion surely.  <P>SOLUTION: Unnecessary harmonic distortion occurs when the analog conversion of quantized data of a minute amplitude signal is carried out, but the unnecessary harmonic distortion can be reduced because a white noise generator 13 in an apparatus 1 for reducing quantized distortion adds minute amplitude white noise to a quantized input signal and whitens harmonic distortion components, and whitened components of low autocorrelation are reduced by an adaptive filter 19. Switching can be performed naturally with no strange feeling because a cross fader 27 outputs an input signal as it is if it has a large level to some extent, and performs switching to the output signal of the adaptive filter only when it has a minute level.  <P>COPYRIGHT: (C)2009,JPO&INPIT
